Add hooks for when spa is created, exported, activated and deactivated. Used by macOS to attach iokit, and lock kext as busy (to stop unloads). Userland, Linux, and, FreeBSD have empty stubs. Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Jorgen Lundman <lundman@lundman.net> Closes #12801
